What's the next number in the series. 65536, 256, 16..?
Artemon [7]
Hi there!

Since
65536 =  {256}^{2}
and
256 =  {16}^{2}
, we would need to find
\sqrt{16}
, which is 4.

So, the answer is 4.

Hope this helps!

from 2002 to 2012, the number of a particular make of cars sold at a dealership yearly declined to 500. The number is expected t
Alinara [238K]
To determine the number of cars that will be sold by the year 2020, we will use the equation,

     N = (N1)(1 - r)^(t)

where N1 is the starting number of cars, r is the rate of the decrease, and t is the number of years from 2012. Substituting the konwn values,

   N = (500)(1 - 0.028)^(8)
    N = 398.38

The closest integer to the calculated value is 398. Thus, the answer is 398 cars.

Is 2 greater Than or less than or equivalent to 30 in
gizmo_the_mogwai [7]
The positive number 2 is 28 numbers less than 30 in, and because you pointed out 30 is in inches I’m guessing 2 is in inches also.

Write the equation of the circle with center (−1, −3) and (−7, −5) a point on the circle.
Pepsi [2]
So, we know the center is at -1, -3, hmmm what's the radius anyway?

well, the radius will be the distance from the center to any point on the circle, it just so happen that we know -7, -5 is on it, thus

\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~ -1 &,& -3~) 
%  (c,d)
&&(~ -7 &,& -5~)
\end{array}
\\\\\\
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
r=\sqrt{[-7-(-1)]^2+[-5-(-3)]^2}\implies r=\sqrt{(-7+1)^2+(-5+3)^2}
\\\\\\
r=\sqrt{36+4}\implies r=\sqrt{40}\\\\
-------------------------------

\bf \textit{equation of a circle}\\\\ 
(x- h)^2+(y- k)^2= r^2
\qquad 
center~~(\stackrel{-1}{ h},\stackrel{-3}{ k})\qquad \qquad 
radius=\stackrel{\sqrt{40}}{ r}
\\\\\\\
[x-(-1)]^2+[y-(-3)]^2=(\sqrt{40})^2\implies (x+1)^2+(y+3)^2=40
